And Bloomberg reports the deal could receive regulatory approval within two weeks. Additionally, Disney CEO Bob Iger told analysts Wednesday morning, “We are already six months into the regulatory process and we are confident we have a clear and timely path to approval.”

But Jefferies analyst John Janedis is confident Comcast could counter yet again, with a bid as high as $US80 billion. “Given the strategic importance of the 21st Century Fox assets, we expect Comcast will come back with a higher offer,” he wrote in a note out to clients on Wednesday.

“Given timing and regulatory risk that could lengthen a path to close, we believe the next counter offer from Comcast will be in the low $US40 per share,” he added.

Shares of 21st Century Fox are up more than 7% Wednesday, and have gained about 40% this year.
